Self-contained breathing apparatus
The Sigma 2 is a first-breath activated, positive pressure, self-contained breathing apparatus. The heart of the Sigma 2 set is a reliable two-stage pneumatic system comprising a positive pressure demand valve, first stage pressure-reducing valve, cylinder connector assembly, shoulder-mounted combined pressure indicator and warning whistle.
This high performance, low-cost equipment is used for shipboard fire fighting and confined space entry. The set complies with the requirements of SOLAS chapter II reg 17.
Sigma 2 is ergonomically designed to be robust and lightweight to ensure optimal load distribution and balance, thus maximising comfort and minimising wearer fatigue. The tempest demand valve and reducer provide excellent flow performance.
The backplate harness is manufactured from flame retardant polyester webbing and features corrosion resistant polyamide buckles and fixings.
The Sigma 2 may be used with the full range of Sabre PanaSeal, PanaVisor, Vision 3 and ProMask PP positive pressure facemasks.
There are only two moving parts to ensure efficiency and reliability. It is easy to operate and has low through-life costs. The shoulder-mounted pressure indicator and warning whistle assembly features photo luminescent face markings for low-light legibility and a robust stainless steel and polycarbonate case with additional rubber shroud.
